Email Validator

Email addresses follow a specific format defined by RFC 5322. A valid email address consists of a local part, the @ symbol, and a domain part.

Email Structure

local-part@domain.tld

Local Part (before @)

• Can contain letters, numbers, and special characters: . _ % + -
• Cannot start or end with a dot
• Cannot have consecutive dots
• Maximum 64 characters

Domain Part (after @)

• Must contain at least one dot
• Labels separated by dots can contain letters, numbers, and hyphens
• Labels cannot start or end with a hyphen
• TLD must be at least 2 characters
• Maximum 255 characters total

Limitations

This validator checks the syntax/format of an email address. It does NOT verify:

• Whether the domain exists
• Whether the mailbox exists
• Whether the email can receive messages
• Whether the email is a disposable/temporary address
